In terms of hardness, VA panel belongs to soft screen and IPS belongs to hard screen.

1 and Fujitsu's MVA technology (multi-domain vertical arrangement technology) are currently manufactured by Chimei Electronics and AUO in Taiwan Province Province, with high market penetration.
2. The viewing angle of the improved P-MVA panel can reach 178, which is close to the horizontal level, and the gray response time can reach below 8ms.
Domestic TV usually likes to use MVA because it is cheap. Mid-range products like PVA.
4. BenQ adopts MVA panel.
5. Both Samsung and Sony use PVA panels (the patterns are arranged vertically). S-LCD is a joint venture between Samsung and Sony.
6. The improved S-PVA can keep pace with P-MVA, and get a very wide viewing angle and faster response time.
7. Sharp uses CPA panel, which belongs to soft screen. In fact, ASV (Advanced Superview, or Axisymmetric View) does not refer to a specific wide-angle technology. Refers to the products that adopt TN+ film, VA and CPA wide-angle technology as ASV. In fact, only CPA (continuous windmill alignment) is Sharp's own wide-angle technology.
8. The IPS (in-plane switching) camp headed by Hitachi has gathered many manufacturers such as LG- Philips and Hanyu Caijing. The panels produced by Hitachi and Taiwan Province Caijing are manufactured by AS-IPS technology.
9. Toshiba and Panasonic are also loyal supporters of IPS technology. IPS Alpha is a joint venture between Toshiba, Panasonic and Hitachi.
10, LG and Philips all use ips panels. LG- Philips improved S-IPS technology. LPL is a joint venture between LG and Philips.
1 1 and TN (twisted nematic) panels are soft screens and the most widely used entry-level LCD panels, which are widely used in mainstream low-end LCD displays in the market. At present, most of the TN panels we see are improved TN+ films, that is, compensation films.
12, NEC's ExtraView technology, Panasonic's OCB technology and modern FFS technology are all improvements on the old TFT panel, providing viewing angle and response time.
The production of large-screen LCD TV needs more than 6 generations of production lines. At present, the global LCD panel production line is mainly controlled by five companies, namely AUO and Chimei Electronics in Taiwan Province Province of China, Sharp in Japan and Samsung and LG- Philips in South Korea. These enterprises supply the panel demand of the world's major LCD TV brand manufacturers.
The large-screen LCD production line that has been built has Sharp 1 8 generation line; LPL 1 7.5 generation; Samsung has two 7th generation lines. The six 6th generation lines are Sharp, LPL(LG- Philips), Huaying, IPS Alpha (Toshiba, Panasonic, Hitachi) and AUO (2 lines); Chimei 1 5.5 generation line. Sharp has decided to build the second 8th generation line, the first 7th and 5th generation lines of AUO have started testing and will be put into production soon, and the 7th and 5th generation lines of Chimei are also under construction. In 2007, we will invest in the 8th generation production line of Samsung Electronics and the 7th, 5th and 6th generation production lines of Chimei Electronics.
No matter what you say online, you should go to the store to see it yourself. According to the actual distance from your home (sofa to TV), you can actually feel it with your own eyes. The best feeling is what you need.
Technically speaking, AS-IPS is the most advanced, S-PVA is only used by Sony and Samsung, ASV is mainly used by Sharp, while S-IPS, PVA, P-MVA and MVA are more common, especially P-MVA and MVA are mainly used by domestic LCD, and S-IPS are mostly used by Philips and LG. However, in terms of visual effects, Sharp's Kameyama Honeycomb Screen ASV has the best effect. Although the technology is very old, its unique physical anti-aliasing function is incomparable to any other screen, and its grasp of dynamic pictures is superb. Secondly, Samsung and Sony use S-PVA panel, and its patented half-pixel lighting technology is in place in detail. Note: Please separate S-PVA from PVA, there is a huge gap between them! As for AS-IPS, we haven't found anything special yet, but it is definitely the most advanced technology, and maybe it has its own uniqueness.
In terms of technology maturity, IPS technology and VA technology are the most mature and effective, while IPS technology is the best, with the best performance and the highest increase in patent fees and costs.
From the perspective of market popularity, the panels produced by IPS technology, MVA technology and PVA technology have the highest penetration rate in the domestic LCD TV market.
In terms of visual angle index, the visual angle of S-IPS, CPA and PVA technology can reach more than 170, and MVA and OCB technology can reach more than 160.
In fact, the wide viewing angle technology is not only reflected in the size of the viewing angle, but also in the change of image quality when the viewing angle changes-that is, color cast, gray scale, penetration uniformity and so on. As far as the relationship between the uniformity of light transmittance and viewing angle is concerned, the performance levels from high to low are S-IPS, IPS and VA in turn.
In terms of black reduction ability, the black restored by IPS technology is slightly worse than MVA, and it is necessary to rely on optical film compensation (AS-IPS) to achieve better black. Sharp CPA technology combines black TFT and improved AGLR technology. By adding a special chemical coating on the liquid crystal surface, the light emitted by the backlight can penetrate the liquid crystal layer better, thus producing higher brightness, lower reflection and stronger black reproduction ability.
IPS is also slightly inferior to MVA in picture details.
In terms of response speed, the fastest is Panasonic's OCB technology, followed by VA technology and IPS technology.
